In addition to include "mysql_upgrade" in a RPM, it should also be called when the RPM is upgraded. support-files/mysql.server.sh: Support getting additional arguments, which need to be passed on to the server. This works only if the server is started through "mysqld_safe", as the IM will not pass such arguments. So if the IM would be used, additional arguments cause the start to fail (voluntarily). This feature is needed so that tools like RPM can start the server in an "isolated" way, see the patch to the RPM spec file (also in this changeset) to call "mysql_upgrade". support-files/mysql.spec.sh: Call "mysql_upgrade" during an RPM upgrade. "mysql_upgrade" needs a server to run, as it issues SQL commands. (This had been neglected previously.) It also needs to connect as "root", but in an RPM upgrade the password is unknown. To allow this, the server is started "--skip-grant-tables". Normally, this would open big security holes, so it is also started "--skip-networking", and access to the socket is limited to "mysql" + "root" by temporarily setting mode 700.

# If you install MySQL on some other places than @prefix@, then you
|
|
# have to do one of the following things for this script to work:
|
|
#
|
|
# - Run this script from within the MySQL installation directory
|
|
# - Create a /etc/my.cnf file with the following information:
|
|
# [mysqld]
|
|
# basedir=<path-to-mysql-installation-directory>
|
|
# - Add the above to any other configuration file (for example ~/.my.ini)
|
|
# and copy my_print_defaults to /usr/bin
|
|
# - Add the path to the mysql-installation-directory to the basedir variable
|
|
# below.
|
|
#
|
|
# If you want to affect other MySQL variables, you should make your changes
|
|
# in the /etc/my.cnf, ~/.my.cnf or other MySQL configuration files.
|
|
|
|
# If you change base dir, you must also change datadir. These may get
|

# overwritten by settings in the MySQL configuration files.
